Title: Improvements in or relating to Controllers for Controlling the Supply of Power to a Load
Inventor: HALL DONALD WILLIAM
IPC: G05D23/24
Filed: 1965-06-24
Abstract: 1,153,725. Automatic temperature control systems. FIELDEN ELECTRONICS Ltd. June 7, 1966 [June 24, 1965], No.26752/65. Heading G3R. A controller for regulating the supply of A.C. power to a load comprises a ramp waveform generator and power switching means controlled to be conductive during a variable portion of the ramp waveform, which waveform has a period extending over several cycles of the supply frequency, and is synchronized to terminate coincidently with the supply current passing through zero, the switching means having an output stage which is supplied with A.C. and is controlled by the summation of the ramp waveform and a power demand signal. In a temperature control system the output of a resistance thermometer is compared with a reference 2 the error being passed through an A.C. amplifier 6 to a phase sensitive detector 5 whose maximum output is greater than that necessary to. fire thyristors in an output stage 3. The detector 5 output is added to that from a ramp generator 4, the sum firing thyristors in output stage 3. At small temperature deviations, the thyristors do not fire until detector 5 output plus the generator 4 output is sufficient, hence the thyristors are fired for one, or several half cycles in succession followed by a dead period, the first half cycle in each series possibly being fired with an angular delay, dependent on the slope of the ramp waveform and extent of the temperature deviation. The ramp generator may comprise a supply current zero synchronized unsymmetrical astable circuit (8, Fig. 2, not shown) producing trigger pulses having a period of several half cycles of the supply frequency, the pulses discharging an integrating circuit (11) to produce a ramp waveform. To improve linearity of the waveform a linearizing circuit (12) may be included, which may be a passive circuit.

Title: Improved manufacture of tri-alkali phosphate from ferrophosphorus
IPC: C01B25/30
Filed: 1933-10-03
Abstract: In producing trialkali phosphates, a mixture of ferrophosphorus and alkali or alkali carbonate is heated at gradually increasing temperature, but always below the fusion point of the mass at any particular stage, the initial and final reaction temperatures being 550--700 DEG  C. and 1100--1250 DEG  C. respectively.  The melting point of the mass at an intermediate stage may be below that of the initial mixture and when a batch-type process is effected, the irregular temperature gradient may be followed.  When a uniform temperature gradient is necessary, as is the case when the process is effected in a rotary kiln, it is necessary to employ an initial temperature considerably below the melting point of the starting materials.  The reaction mixture is heated in the rotary kiln preferably by a countercurrent blast of heated gases from the combustion of petroleum hydrocarbons.
